This device was bought to organize a video surveillance system in the country and this is its main function, i. E. traffic from video cameras on demand should be sent to the cloud from where I can already watch it, and the device copes with this task 5+. Plus, it has an output for connecting a landline phone, which is convenient for me, now there is another way to call. I could not catch the 4G signal, I work only in 3G, I have been sitting on body2 for more than 2 years, since it appeared in Hong Kong. region, the quality of communication is excellent. Video 1080 x 15 frames / sec from 4 x cameras transmits without problems, through the NVR of course, but IP cameras. I tested the speed for receiving about 12 Mb / s, for the return of 4-5 Mb / s, this is enough to watch the video on the mobile and on the computer. Didn't notice any dependencies. No battery - for me it does not matter, since the system provides backup power from a 12V battery. In general, a good device for my tasks, I'm 100% satisfied. I ADD: I worked for 4 years, I confirm everything that is described above, now 4G has appeared, respectively, the speed has increased, plus the tariffs have fallen in price, now I use it as the main router in the country. speed 25-30 for download and 6-10 for return. I watch 1080p movies from youtube, the computer slows down when playing, but there is no stream. I stopped hanging, I think it was because of the SMS that the operator sent, now it does not hang. A very convenient function of a landline phone and SMS can be sent via the WEB interface.
